Christos Tsapelas

I am working as research associate at Athena Reasearch and Innovation Center, under the supervision of Dr. Georgia Koutrika. My research interests lie on the intersection of Machine Learning with Database Systems, especially on applications of Deep Learning for query optimization and applications of NLP on various assest of DBMS. Currently I am working for FAIR Core 4 EOSC project, responsible for NL search services over OpenAIRE Research Graph. I am working also as teaching assistant for the Database Systems, course of Data Science and Information Technologies program.

I received my MSc degree from Data Science & Information Technologies program, with a specialisation on Big Data & Artificial Intelligence, at the University of Athens. My thesis implements the concept of a neural-based optimizer combining both data and queries using variational inference. I received my BSc degree in Computer Science from the same faculty, titled Pathlet Learning for Compressing and Planning Trajectories under the supervision of Dr. Dimitris Gunopoulos.
